This study presents a deep-learning-based framework integrating a single heat-flux sensor for rapid and accurate estimation of core body temperature (CBT). A gated recurrent unit (GRU) model was trained using a large-scale dataset comprising finite-element simulations and experimental transient responses to learn conduction- and convection-governed features. By analyzing only the initial 30 s of temperature signals, the model achieved a mean absolute error below 0.1 °C across a wide range of ambient temperatures (5–35 °C), convective heat transfer coefficients (0–50 W·m⁻²·K⁻¹), and skin conductivities (0.32–0.50 W·m⁻¹·K⁻¹). This data-driven approach eliminated the need for prolonged thermal stabilization, enabling site-independent CBT prediction with reliable performance under dynamic environmental and physiological conditions.
